22-year-old is jailed on unlawful sex charge in Santaquin

SANTAQUIN  A 22-year-old man was booked into Utah County Jail Monday, accused of unlawful sexual activity with a minor and custodial interference.

Police say the man, who was living in Santaquin, helped his 15-year-old girlfriend run away to Mexico while she was pregnant with their child.

The girl was reported missing in September.

Police who were investigating her disappearance eventually were able to speak with the girl by telephone.

In late January, the two were taken into custody by U.S. Customs agents at the border near Yuma, Ariz. The girl was reunited with her parents and he was held in Arizona until his arrival in Utah, according to a police report.
